I found a solution: nnoremap <leader>r :w \| !racket -e "$(grep -v '\#lang' %)" -i<cr>
This little hack, instead of enter!ing a file, simply echoes the contents of the file into the -e argument using a subshell. Racket treats newlines the same as spaces, and ignores blank lines, but if you're a neat freak, you can do: nnoremap <leader>r :w \| !racket -e "$(grep -Ev '(\#lang)\|(^$)' % \| tr '\n' ' ')" -i<cr> On Friday, 30 November 2018 01:36:11 UTC, Habib Alamin wrote: > > Hi, > > I'm trying to set up a keybinding in my editor to enter the namespace of > my current file in a REPL, similar to how Dr Racket's Run button works. > > I can do a racket -e '(println "Hello!") -i and it loads the REPL after > printing Hello.
